Tesla will be discontinuing the Model S 60 and 60D sedan on April 17, 2017. The announcement made by Tesla via email to Model S customers across Europe (there’s been no reports of US customer receiving the email at the time of this writing) comes on the heels of a series of discontinuations aimed at maximizing production efficiency.

Tesla confirmed with Teslarati that the current base version of the Model S which is capable of 210 miles to 218 miles of range depending on motor configuration, will be available until mid-April. Both Model S and Model X will share the same battery configurations following next month’s discontinuation of the 60 kWh battery pack, leaving the 75 kWh pack as the entry level battery option.

Though there’s been no official statement made by the company on why the current entry level Model S will be removed, in favor of bumping the base version to a Model S 75 and 75D, one can presume that demand for the 60 kWh battery pack was low. Tesla discontinued Model X 60D last October presumably, also, due to unpopularity of the range offering. One can also speculate the Tesla is looking to create as much as a gap as possible between a fully optioned Model 3 and the base Model S. By minimizing overlap between two vehicles aimed at very different target audiences, Tesla can minimize potential cannibalization of Model S sales.

Discussion taking place within the Tesla community seem to suggest that Model 3 could be offered with a battery pack up to 75 kWh in capacity, further validating Tesla’s move to discontinue the Model S 60D in order to avoid overlap. Removing the $68,000 base version of the Model S also leaves room for Tesla to set a higher price cap for a fully-optioned Model 3.
